LightningGSX - Are you implying that the EVO VIII twin scroll turbo (9.8cm2) imposes a HIGHER exhaust restriction than a standard non twin scroll 7cm2 housing ? :confused:
Please clarify. If each pair of cylinders get essentially 4.9cm2, then wouldn't that be the same back-pressure if not better. I don't think your giving anything up with the twin scroll turbine housing. Most likely just more expensive to manufacture, but better technically since the exhaust pulses are out of phase with each other until contact with the turbine.
No actually I'm not.You're not giving anything up with the twin scroll, it a far superior design.It will flow as much, if not more, than a single scroll housing of the same area, and still have excellent spool up qualities.
